Customer Feedback

I have been using K&N brand filters since 1997 when I installed my first on my
Dodge Neon. Wow was the reaction I received then and it remains that way
to date. I have now installed K&N filters on all of my families cars and
are now moving on to friends, neighbors, and anybody who complains of
performance in their car. The most amazing Install was probably on a 1990
Ford Mustang 4 cylinder. It had lost it’s get up and go and with a bit of
pipe and a K&N filter it was renewed. The owner paid me for telling him
about it.

Keep up the great work.

Simply the BEST on the market. I have used them in all of my vehicles. They are easy to install and you will immediately notice a boost in power and a small improvement in the gas mileage. Easy to clean and very durable.
Spend the extra money and try one in your car or truck. You will save that money the first year in gasoline. I have them in my 2014 Mustang V6 Coupe and my 2013 Ford Explorer XLT V6.
